The Eee PC has revived the world of tiny notebooks with a cheap price, which made a lot of companies create their own computer with a basic configuration, and obviously, a low-budget cost.

With that being said, here is the $400 UMPC made by 3K Computers, and named RazorBook 400. The Ultra Mobile detail makes the LCD screen size be very small - 7-inches - and therefore the resolution is also low, at 800×400 pixels.

The “engine” of the RazorBook 400 is a 32-bit Single Core Mobile Processor @ 400 MHz, backed up by 512MB of RAM memory, and 4GB on the internal flash drive.

- WiFi connectivity
